Make has trouble with targets containing whitespace, 
http://savannah.gnu.org/bugs/?712, so the general approach is
to use relative paths where possible.  It's generally only Emacs
itself that needs absolute paths, eg in src/epaths.h.

* configure.ac (srcdir): Don't make it absolute - abs_srcdir exists.

* Makefile.in (abs_srcdir): New, set by configure.
(buildlisppath): Use abs_srcdir.
(install-arch-indep, install-etcdoc, install-info, install-man)
(install-etc): Quote entities that might contain whitespace.

* admin/unidata/Makefile.in (emacs, ${DSTDIR}/charprop.el):
Quote entities that might contain whitespace.

* leim/Makefile.in (abs_srcdir): New, set by configure.
(buildlisppath): Use abs_srcdir.
(RUN_EMACS, .el.elc, changed.tit, changed.misc, leim-list.el)
($(srcdir)/ja-dic/ja-dic.el, setwins, distclean, check-declare):
Quote entities that might contain whitespace.

* lib-src/Makefile.in ($(DESTDIR)${archlibdir}):
Quote entities that might contain whitespace.

* lisp/Makefile.in (abs_srcdir, abs_lisp): New, set by configure.
(emacs, compile, compile-always):
Quote entities that might contain whitespace.
(custom-deps, finder-data, autoloads): Use abs_lisp.
($(MH_E_DIR)/mh-loaddefs.el, $(TRAMP_DIR)/tramp-loaddefs.el)
($(CAL_DIR)/cal-loaddefs.el, $(CAL_DIR)/diary-loaddefs.el)
($(CAL_DIR)/hol-loaddefs.el): Manually expand target file name.

* nextstep/Makefile.in (${ns_check_file} ${ns_appdir}):
Quote entities that might contain whitespace.

* nt/Makefile.in ($(DESTDIR)${archlibdir}):
Quote entities that might contain whitespace.

* src/Makefile.in (RUN_TEMACS): Make relative (again).
($(leimdir)/leim-list.el, .el.elc, $(lispsource)/loaddefs.el)
(bootstrap-emacs$(EXEEXT)):
Quote entities that might contain whitespace.

* test/automated/Makefile.in (abs_top_srcdir, top_builddir):
New, set by configure.
(top_srcdir): Remove.
(abs_test, abs_lispsrc): New.
(lisp): No longer absolute.
(emacs, lisp-compile, compile, compile-always):
Quote entities that might contain whitespace.
